MIXER FOR CULINARY USE.

T all whom it may concern:

Be it known that 1, Elmer SCHMITZ, a citizen of the United States,residing at Chicago, county of Cook, and State of lllinois, haveinvented certain new and useful Improvements in Mixers for Culinary Use,of which the following is a specification.

My invention relates to mixers for culinary use and particularly tomixers characterized by a receptacle and a rotary dasher suspendedtherein.

The object of my invention is to provide a mixer of the class mentionedhaving a suit able frame, a receptacle removably mounted therein, arotary dasher detachably mounted in said frame and suspended within thereceptacle and suitable drive mechanism fixed to said frame, andequipped with means for locking the receptacle and dasher in the frameand means to prevent operation of th device except when in lockedposition.

A further object of my invention is to provide a device as mentioned,which shall be of simple construction, easy to operate, of low cost tomanufacture and one which shall not readily get out of order.

Other objects will appear hereinafter.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification, and inwhich,

Figure 1 is a front elevation of a mixer embodying my invention in itspreferred form, Fig. 2 is a top plan view thereof, Fig. 3 is a sideelevation with a portion of the side of the receptacle broken away toshow the dasher, Fig. 4 is a perspective view of the dasher, the partsbeing segregated and Fig. 5 is a horizontal section of the dasher nearits upper end.

The frame of the device comprises a base 1, a pair of uprights 2, a yoke3 and an upper frame portion 4, from which a dasher is suspended andwithin which the driving mechanism is arranged. The base 1 is preferablyof wood but may be formed of metal if desired. The uprights 2 of theframe are formed of flat bars of metal having their lower ends bent informing feet 5 by which they are bolted or otherwise secured to thebase. The members 2 extend vertically upward for a considerable distanceand are then mchned inwardly as at 6, and their upper ends are bent in ahorizontal position formmg flanges 7 by which they are secured to aSpecification of Letters Patent.

horizontally disposed plate 8. The yoke 3 is riveted or otherwisesecured to the vertical portions 2 at about midway of their height, andis arranged or provided with the parallel and horizontal arms orextensions 3. The upper frame 4 is formed of a single bar of metal bentto form the horizontal portion 9 which is secured to the plate 8, thevertical portion 16 and the horizontal upper arm 11 arranged above andparallel with the arm or portion 9.

12 indicates the receptacle which is preferably a cylindrical member ofthin sheet metal open at the top and having a rounded or hemisphericalbottom 13. The receptacle is provided with the trunnions 14 by which itis mounted upon the ends of the arms 3 of the yoke, the upper edges ofthe arms being provided with notches 15 to receive them. The trunnionsare arranged above the center of the receptacle hence the latter assumesan upright position when mounted in the frame. The receptacle isprovided with a closure which comprises a disk 16 having a dependingflange 17 which fits snugly about the up per edge of the receptacle.

The dasher is formed of a pair of similar ti at skeleton plates arrangedin planes which intersect at right angles to each other. Each plate isshaped to conform to the vertical section of the receptacle and is butslightly small er than the inner dimensions of the same.

Referring to Fig. 4 of the drawings 18 indicates one of the skeletonplates and .19 the other. These each comprise a rectangular upperportion conforming to the cylindrical portion of the receptacle andcomprising the horizontal bars 20 and 21 and the vertical bars 22 and23, and a semi-circular lower portion conforming to the curve orhemispherical bottom 13 and comprising the semi-circular portions 24 and25 which are extensions of the bars 22 and 23 respectively. Each frameis completed by a broad central bar 26 extending throughout the heightof the frame from the top bar 26 to the bottom curved portion 24. Thebar 26 of the frame 18 is slotted as at 27 from the top downwardly andthe bar 26 of the frame 19 is similarly slotted as at from the bottomupwardly. Each frame portion of the dasher is stamped out of a singlepiece of flat metal, and the device is assembled by sliding the frameslongitudinally one upon the other, the slots 27 and 28 accommodating thecorresponding unslotted portions of the opposite frame.

29 indicates the dasher shaft. This is formed of a rod to the lower endof which is secured a sleeve or tube 30. The tube 30 extends below thelower end of the rod 29 and is slotted as at 31 to receive the portions20 of the dashcr. After the parts are assembled. they are securedtogether by soldering. The shaft 29 extends above the arm 11 of theframe and the portion above said arm is slightly enlarged in diameterforming a head 32. The arms 9 and 11 are above and parallel with theaxis of the trunnions 14 and their front edges are notched as at 33 toreceive the shaft. After the receptacle and the dasher are placed in theframe, in sub stantially the position shown in dotted lines in Fig. 3,they may be swung upon the trunnions until the shaft enters the notches33.

Secured to the shaft 29 above the arm 9 is a gear 34. which meshes witha gear mounted in the frame portion 4 upon a shaft 36 journaled in asleeve 37 extending horizontally from the vertical portion 10 of theframe. Secured to the outer end of the shaft 36 is a crank 35 by meansof which the dasher or agitator is operated. The gears 34 and 35 may beof any desired. form but I prefer to employ the spur gears shown in thedrawings which are stamped out of heavy sheet metal. Pivoted to theframe 4- as at 39, is a latch 40 by means of which the shaft 29 islocked to the frame. The latch 40 turns down in front of the upper notchand is provided with an inwardly extending lip 41 which engages the headof the shaft. When the shaft is locked. the receptacle is also looked inthe frame, but when the latch 40 is thrown back as shown in dotted linesin Figs. 1 and 2, the receptacle and the dasher may be freely removedfrom the frame. To prevent the weight of the dasher shaft from tiltingthe receptacle sufficiently to spill its contents, the portions 2 of theframe are arranged behind the receptacle, and the bottom 13 engages thesame when tilted to the position shown in dotted lines in Fig. 3.Suitable means are provided to prevent turning the drive mechanismexcept at such times as the shaft is locked in the frame. This comprisesan ear or lug 42 on the latch 40, which, when the latch is thrown backenters between the teetn of the gear 35 preventing the gear fromrotating.

The shaft 29 passes through the closure 16 and the closure is providedwith an upwardly extending sleeve 43 forming a bearing for the shaft tokeep the dasher properly centered in the receptacle. The closure is alsoprovided with a depending annular flange 44 surrounding the shaft whichprevents the agitated material within the receptacle from being ejectedthrough the sleeve 43.

Having described my invention what I claim as new and desire to secureby Letters Patent, is:

1. In a device of the class described, a frame comprising a pair ofupright members connected substantially midway of their height by ayoke, and an upper frame portlon, in combination with a receptacletrunnioned on said yoke, a dasher suspended within said receptacle andhaving a shaft detachably mounted in said upper frame portion, drivemechanism fixed in said frame and a gear fixed to said shaft and meshingtherewith, substantially as described.
